I'll give this a shot today I think re: heat shrink. I love the X10's so far, but, they do seem a little fragile.My thought was to use red heat shrink on the R and black on the L. It would be functional but I think it might ruin the looks of them.
I really like the clarity of & vocals are very good. Fun IEM for me. Of course these are probably the nicest IEMs i've had to date. I hope they hold up to use. I haven't tried wearing them w/cable over the ear yet. Seems like that would work well with the cable being so flexible.
